Not always.
1. Today the Mpemba effect remain unclear and possible not true. 2. I suppose that any link exist between the so called Mpemba effect and the freezing of rubbing alcohol.
yes
The Mpemba effect is named after a Tanzanian high school student Erazo Mpemba, who discovered it in the 60's. His class was making ice cream, where they used boiled milk and cooled it before mixing it in and freezing it. Mpemba wanted room in the freezer for his ice cream, because it was getting full, so he put it in without waiting for the milk to cool. To his surprise, his was frozen first. His teacher laughed at him, but he got help from a visiting professor, and they discovered it was true! :D
The scientist Mpemba discovered the Mpemba effect, which is the phenomenon where hot water freezes faster than cold water under certain conditions. Despite being initially met with skepticism, the Mpemba effect has been observed and studied in various experiments.
is when hot water freezes faster then colder water (or other liquids)
Erasto Mpemba was born in 1950.
Erasto B. Mpemba was a Tanzanian schoolboy who first observed the Mpemba effect - the phenomenon where hot water freezes faster than cold water under certain conditions. This discovery has intrigued scientists and researchers for years and has been the subject of numerous studies and debates.
yes they alaways fall of the tree. yes they alaways fall of the tree.
Yes. It is a proven fact by scientist that hot water will freeze faster than cold or warm. This process is called " The Mpemba Effect ".
The Mpemba effect is a phenomenon where hot water can freeze faster than cold water. In life science, this effect has been studied in various contexts, such as understanding the thermal properties of living organisms and how temperature affects biological processes like metabolic rates and enzyme activity. It can provide insights into how organisms respond to temperature changes and adapt to different environments.
cold waterA2. But before you close your mind, check out the Mpemba Effect in Wikipedia.And to further improve your knowledge check out the Leidenfrost effect.
An unresolved question! See Mpemba Effect in wikipedia for the best experimental conditions for this anomaly!
